Re: [nafex] Jim Fruth's comments.

The assumption that black fruit is less visible to birds is not correct. Fruit eating birds see further into ultraviolet than humans. A black fruit may, in fact, be much brighter in the UV than we can detect with out eyes. Fruits can signal ripening by changing color. We all know that. But we cannot see with our eyes how that ripe fruit may appear to birds. My source is an excellent article that appeared in Scientific American magazine many years ago. I am not able to locate the actual reference, but someone more skilled than I can likely find it. As I recall, part of the article did discuss how changes to UV fruit color was used by birds to detect ripening fruit.

What about
honeyberries/haskaps?  The birds eat them all the second
they
ripen.  Jim, have you tried blue
beads on honeyberries or blueberries?
